A "spoiler" is a fact that gives away something about the plot or story, in this case a revealing photo and blurb. Described that way probably because it originated from the practice of telling the ending of a movie to somebody before they saw the movie, a spoiler.

Didn't find the exact spoiler you mention but by freezing and rewinding slightly at 48.00 seconds ( comes in at roughly 49.00 and lasts through 51.00 seconds ) in this preview:http://www.starz.com/titles/BackToTheFuturePartII I see a sideview of a metallic blue Concord wagon and a bare glimspe of the tailend 3/4 view( located in the upper left corner under a big lit billboard ) of what looks like either a Bittersweet Orange with cream 1/4 vinyl roof or Calcutta Russet Red ( hard to tell given the lighting ) Javelin. Yes?
